Answer 2

Differences between IR and FTIR spectroscopy

Explanation:

• IR means Infrared spectroscopy whereas FTIR stands for Fourier Transform Infrared spectroscopy.
• IR uses a single or monochromatic system whereas FITR uses Michelson interferometer and employs a number of scans.
• IR is a relatively slower technique whereas FITR is faster than IR.

• Preparation of sample in IR takes longer time, whereas these days ,FTIR uses Attenuated Total Reflection (ATR), where there is no requirement for sample preparation.
